@sm0olr I’d say software devs are exceptionally hostile about AI in general. Look at HN comments. I doubt most of them will be working in the industry in 5 years.

@skalskip92 Amazing performance. Any chance it can do instance segmentation any time soon?

@mwmoedinger This is an excellent list! Bookmarking for our upcoming renovation

10 unconventional (and maybe counterintuitive) ways to save money on a residential renovation! (2+3 you already know, if you've followed me for a while. Keep going, there's other stuff in the list too!!) Read on: 🧵

@Protons4B @robertjwhitney I considered one for my flat but I couldn't make the upfront cost work (versus an electric shower). Quite expensive and not cheap to install either.

@robertjwhitney They have their niche - essential for some properties.

Sunamp hot water heat batteries

@JonathanWaxman1 Agreed the governments have done a good job with CfD and disincentivising coal, but it’s likely that would have happened under other govts too, with wind and solar getting cheaper. What’s the alternative history? Do we say ‘good job for not being a blocker’? (also, onshore wind).

My timeline which leans massively to Labour / left portrays the last 15 years of Conservative led governments as having been terrible in every respect. I don’t find this a very balanced assessment. The progress on renewable energy - a key climate pillar - has been just huge.

@mwmoedinger There's a great book, 'The Warm Dry Home', which looks at how humidity becomes an issue in older buildings, not because of design issues, but maintenance issues, like water ingress, condensation, blocked ventilation, and ground levels around the house. (shop.heritage-house.org/product/book-t…)

The single biggest enemy of buildings? Humidity and water. The second biggest? People doing the wrong things to try to mitigate it. I've seen it time and time and time again. A lot of what I do is forensic/diagnostic in nature: trying to piece together a picture of what's happening, so we can begin to come up with solutions. In old houses, problems can be developing unseen for decades, and/or people attempt fixes that make it worse A basic understanding of physics (statics/dynamics and thermodynamics) goes a really, really long way toward being able to solve mysteries. When you understand the principles, you can start to understand how they manifest out in the wild. And also...patience. Take your time to mull the problem, to let the problem make itself known to you. Moving too fast, or being too sure of yourself, can be disastrous. Buildings are *incredibly* complex, even the "simple" ones! The building *will* tell you what's wrong, you just have to ask it the right questions and keep your eyes and ears open. And...beware the old adage "when you're carrying a hammer, every problem looks like a nail." If you call the guy who makes his living by coating the inside walls of basements, he'll tell you that's what will solve your water intrusion problem. But, he's not looking at the bigger picture, at the building as a *system.* I love helping people solve mysteries, but honestly, most people aren't willing to take the time to do things right. They'll even pay more money for a quick fix bc it "sounds good" then listen to folks who think about this stuff the right way. People expect that I should know instantly what's going on (sometimes I do, but most of the time I need to see it a couple times, do some thinking, etc) and they expect that I have the solution exactly right immediately. Most of these tough issues (like my HVAC post the other day) aren't like changing a tire on a car, where the problem and the solution are obvious. We may only be able to see symptoms of the real problem, and we may not be able to get further vital info without ripping out tons of finish materials. So we rely on experience, understanding the concepts of physics, and careful observation of what we *can* see - as well as patience and understanding from our clients as we work to get to the bottom of whatever is going on. It ain't easy, but I love it.

@MattZeitlin Big assumption: that the commute involves driving. If you're walking, cycling or even taking some form of subway / rail, it can be healthy and pleasant.

There are pluses and minuses to office and remote but there are no pluses to most commuting: bad for people’s physical and mental health, bad for the environment, bad for other drivers, purely wasted time

@timothymortimer @betateach @heatpolicyrich @theheatinghub It's also worth keeping in mind that Swansea is very exposed to wind-driven rain and that the cavity is there for a reason. In less exposed areas, it's less of an issue. Exposure map here: felt.com/map/UK-Exposur…

I’m feeling increasingly justified for avoiding this industry like the plague: Homes insulated in government scheme go mouldy bbc.com/news/articles/… Too many horror stories to practically and reliably recommend? @betateach @heatpolicyrich @theheatinghub

@AnnieLeymarie @PeteK_AQ Did you install it yourself or did you find a good installer? I'm keen to install something like this but struggling to find someone who knows what they're talking about.

@PeteK_AQ (I've installed this fresh-r.eu/en/)

I use this air cleaner in my bedroom. It is quiet enough to sleep and is effective in moderate air pollution. If you’re suffering a wood burning neighbour, then you’ll need to get the Blast Mini (if you have space) and some ear plugs. In addition to council involvement, ofc

@Zapaman @EcoHome_Lab @EnergySysCat @Protons4B @LFE_Foundation @Openenergymon Yes, I'd love that too if it exists

@EcoHome_Lab @EnergySysCat @Protons4B @LFE_Foundation @Openenergymon Please provide a video of session if possible

REMINDER: Tonight's session at 6pm! Metered Energy Saving methodologies for evaluating success in UK #retrofit, with Connor Galbraith of @EnergySysCat - all welome! meetup.com/eco-home-lab-m…

@Polycam3D I've actually done this in advance but found that rental companies care about tiny scratches that don't show up in the 3D scan.. This was two years ago, maybe I should try again with gaussian splats...

Ever thought of 3D scanning when renting a car? By doing this both you or rental agencies can capture precise details of any vehicle’s condition before you hit the road.🚙 In case of accidents these scans can provide evidence for quicker resolutions. 👀

@ETWriteHome I think about this all the time as well. It was so brilliantly named. (Also never went).

I think far too frequently about the pizza, chicken and falafel place that used to exist in Stoke Newington called Chickpizz. One of my greatest regrets is never having gone there. They won business naming forever.

@AnnieLeymarie @heatfutures @ZeroCarbonWorld @granddesigns @Kevin_McCloud @MLiebreich @nesta_uk @betateach It's changed a lot since the outrage started but yes - I agree, A2A is best for single room and should be explored more!

@heatfutures @ZeroCarbonWorld @granddesigns @Kevin_McCloud @MLiebreich @nesta_uk @betateach @rdzeldenrust As a lay person about to open my home & try my best to give general guidance I couldn't see major howlers in the article, with its provisos (apart from maybe heat pump COP/SPF) BUT: I would add that an air-air heat pump may be best option for single room - as done in my house!

granddesignsmagazine.com/heating/electr… The most irresponsible piece of home energy journalism ever written? This isn’t marked as an advertorial so I’m going to say yes @granddesigns @Kevin_McCloud you should be ashamed of yourselves (@MLiebreich @nesta_uk @betateach) h/t @rdzeldenrust

@betateach @suburbanpirate @heatfutures @granddesigns @Kevin_McCloud @MLiebreich @nesta_uk @daveludlow Also, he could have looked up some of the numbers / principles in the article he links to (and wrote) (granddesignsmagazine.com/heating/how-mu…) which does get things mostly right

@betateach @suburbanpirate @heatfutures @granddesigns @Kevin_McCloud @MLiebreich @nesta_uk @daveludlow I hope so, but it did look a lot like the article was written with a specific end goal in mind (sell infrared / electric heaters). If it was unconscious incompetence, it would surely be retracted

@philipsargent @AbigailDombey 1) deriving consumption from a device's maximum output 2) using the thermal output of an ASHP as electrical consumption, ignoring COPs of 300%+ 3) equating single room heating with whole house heating 4) assuming 40% higher efficiency for IR when they are controlled on air temp

@AbigailDombey List them ? I can't see anything wrong with it...

@philipsargent @ACJSissons The 0.3012 there is the price per kWh of electricity, so he's not applied any COP as far as I can see.

@ACJSissons Which is what he says, later on in the article. And last time I looked, 10 x 0.3012 = 3.012 correctly.

Two rookie mistakes here: 1) A heat source very rarely runs to max capacity, whether it’s a 10kW heat pump or a 30kW boiler 2) The 10kW figure is the output of heat. A heat pump typically uses about 3 times less electricity than it outputs (so 3 or 4kWh of ⚡️for 10 kW of heat)
